Title: Illuminated roadway divider
Inventor: WARREN CLIFFORD T
IPC: E01F9/541
Filed: 1995-03-10
Abstract: Vehicles are often in collision with the nose section of concrete road dividers, particularly during night-time hours. The invention proposes an illuminated nose section divider with a self-contained energy source. The energy source may be a battery, fuel cell or solar cell. The device would provide 24-hour a day illumination to improve the visibility of these roadway dividers in areas where hydro-electric power is not available or too costly to provide.

Title: Flushable ph-sensitive ostomy pouch containing its own ph modifier
Inventor: SCHNEIDER BARRY L
IPC: A61F5/44
Filed: 1995-03-20
Abstract: A flushable ostomy pouch having side walls composed of pH-sensitive material capable of dissolving when exposed to an aqueous fluid having a pH substantially above or below a neutral pH level, and containing a quantity of pH-modifying material to initiate dissolution of the pouch when it is discarded in the water of a toilet bowl, is disclosed.  The pouch includes a pair of side walls and an external membrane that extends along at least one of the side walls to define a pocket adjacent to that side wall.  A quantity of pH-modifying material is contained in the pocket which, when exposed to a generally pH-neutral fluid entering the pocket, is capable of changing the pH of the fluid in the pocket to a level above or below the neutral pH level. The external membrane is formed such that, when the pouch is discarded in a toilet bowl, it allows aqueous fluid to enter the pocket and contact or dissolve the pH-modifying material, thereby causing the fluid entering the pocket to attain a pH substantially above or below the neutral pH level and dissolve the pH-sensitive side wall adjacent to the membrane.
Patent CA-2145138-A1 (CA)
Inventor: BIRD WARREN M
IPC: B23D61/12
Filed: 1995-03-21
Abstract: A variable thickness linear saw design is proposed for enabling maximum reduction of the thickness of the kerf associated with such saws. Typically, such saws have cutting teeth mounted on the leading edge of a supporting plate. In the improvement of this saw, this supporting plate is given two discrete thicknesses relative to the kerf. A first and narrow thickness (relative to the kerf) longitudinal segment is used parallel to and adjacent the supported teeth. This first and narrow thickness longitudinally extending segment only occupies a fraction of less than half and preferably about 20% of the full width of the saw behind the supported teeth. A second and expanded thickness (relative to the kerf) longitudinal segment is used for the remaining width of the saw. The reduced thickness of the narrow tooth supporting section of the saw forms in the case of the linear saws a preferred exit path for sawdust, this preferred exit path being immediately adjacent and behind the supported teeth of the saw. A variable thickness linear saw of the proposed design exhibits greater lateral stiffness than does a conventional linear saw of uniform thickness. Further, the saw can be subject to greater tension to resist deflection.      Finally, the narrow linear segment supporting the teeth can be shown to have superior resistance to gullet cracking when incorporated to band saw construction. Tension increases in such band saws up to approximately 40% for a given width of kerf can result with consequent improved resistance to transverse forces and improved linearity of the kerf.

Title: Horizontal boring pipe penetration detection system and method
Inventor: STATON RAYMON R
IPC: G01V1/24
Filed: 1995-08-15
Abstract: A method and apparatus for detecting pipe penetration by the bore head of horizontal boring machine utilizes acoustic and seismic sensors.  A sensitive acoustic microphone is placed in the bottom of the nearest sewer manhole to the location of the bore head to detect acoustic signals transmitted through the ground by the bore head for producing a first output signal.  A seismic pick-up device is placed in the vicinity of the bore head to detect vibrations of the ground caused by the bore head, as it moves through the ground, to produce a second output signal.  These first and second signals produced, respectively, by the microphone and the seismic pick-up device, then are supplied to a two-channel strip chart recorder, which provides an output indicia permitting simultaneous comparison of the two signals.  Particular patterns of these detected signals are indicative of the penetration of a sewer pipe.  In addition to these two signals, analysis of the pressure on the bore head by the boring machine also may be made and compared with the output signals produced by the microphone and seismic pick-up device, as a further input to determine whether penetration of a sewer pipe has been effected.

Abstract: There is disclosed a photosensitive automatic controller for use with window coverings in particular for use with venetian blinds. The controller includes a reversible motor, a drive circuit, a photosensitive sensor, a user input, a control signal processor, a command circuit and a feedback sensor. The reversible motor is operably connected to the opening and closing device and it has a predetermined range from open to closed which corresponds to the window covering being fully opened and fully closed. The drive circuit is operably connected to the motor for generating a drive signal which drives the motor in a predetermined range from opened to closed. The photosensitive sensor generates a sensor signal. The user input generates an input signal. The control signal processor is operably connected to the photosensitive sensor and the user input and the sensor signal is combined with the input signal to produce a control signal. The feedback sensor is operably connected to the opening and closing device and generates a feedback signal. The command circuit is operably connected to the drive circuit, control signal processor and feedback sensor and compares the feedback signal to the control signal and produces a command signal which is transmitted to the drive circuit. The controller may include a comparator for ensuring that at night when it is dark the blinds are closed. Further, the controller may be adapted so that a series of blinds may be ganged together with one blind being a master and the remaining being slaves.
